The process in photosynthesis that uses energy from the sun is the process of combining carbon dioxide and hydrogen. To understand why this is the correct answer, let's break down the different options:
1. Splitting water into hydrogen and oxygen: This is part of the photosynthesis process, but it does not directly use energy from the sun. Instead, it is the result of the energy absorbed from the sun being used to split water molecules.
2. Releasing oxygen: Again, this is part of photosynthesis, but it is the byproduct of the process and not the direct use of solar energy.
3. Combining carbon dioxide and hydrogen: This is the step where solar energy is absorbed and used to convert carbon dioxide and hydrogen into glucose, a sugar molecule that serves as a source of energy for the plant.
4. Absorbing carbon dioxide: Plants do absorb carbon dioxide from the atmosphere, but it is not the process that directly uses solar energy.
Therefore, option 3, combining carbon dioxide and hydrogen, is the correct answer as it directly involves the use of energy from the sun in the process of photosynthesis.
